The user’s prize: A signed 18-inch-by-24-inch oil painting of a blue American flag featuring a part of the Pledge of Allegiance, which had a starting bid of $0.99.

The identity of the buyer is unknown, but according to the listing, the winning auction bid was one of 96 by 24 users when bidding closed at 9:55 a.m. Saturday.

Using the EBay account “therealgeorgez,” Zimmerman, 30, put his artwork up for auction early this week.

"Everyone has been asking what I have been doing with myself," the listing reads. "I found a creative way to express myself, my emotions and the symbols that represent my experiences. My art work allows me to reflect, providing a therapeutic outlet and allows me to remain indoors :-)"

Zimmerman was acquitted of murder this year in the shooting death of 17-year-old Trayvon Martin in Sanford, Fla., in 2012.

Since then, he's remained the public eye. He has been detained twice, on suspicion of threatening his wife, and then his girlfriend, with a gun. In the first instance he was not arrested. In the second case, his girlfriend dropped the charges early this month. He picked up his confiscated weapons from the Seminole County Sheriff's office Thursday.

In the question-and-answer section of the post, Zimmerman, who signed off on responses as “your friend, GZ,” received “kudos” from commenters.

“Awesome George!!! Great painting -- wish I could afford it ;) ... Your resilience is astonishing and inspirational,” one wrote.

“Just wanted to tell you we all love you and stand behind you,” another said.

In addition to the painting, Zimmerman promised something else to the highest bidder:

"Whoever wins within the Continental United States, will receive this painting delivered by me personally," he wrote.
